Judging by how the Australians have tried to control pests in the past this seems a bit risky to me. KHV is still not fully understood yet and scientists and fisheries around the world are working their hardest to control its spread. So far there isn’t a cure for this virus and although Australia is an isolated landmass it’s not out of the question that it could be transported elsewhere. This disease needs a cure before we can wilfully release it into the wild.

This plan of viral infection is idiotic at best.There may be no short term effects on the environment, but give it time, and something shitty will come of it. The virus could mutate and spread to ”non pest” fish. Why doesn’t somebody harvest these fish for starving people(there are recipes for carp out there),or use them as fertilizer for crops, or just sell them as pets to rich shmucks? I’m also certain that croc farmers could use them to feed to their crocodiles.
